Page Load Slow Since Update

I have been having page load speed issues today and whilst it may not be fully down to the plugin update I believe there is an issue that needs to be resolved.

I ran my page through GTMetrix and when looking at the waterfall one of the lines is red and it appears to relate to the Team plugin, it is the following link that is throwing up a 404 error and I believe this is causing the page load to delay?

https://www.silverscalesflytying.co.uk/wp-content/plugins/team-members/inc/js/tmm.js?ver=4.9.4

When expanding the line there is the following information that may help:

btw the new screen layout looks good and more user friendly.

Thanks
